摘要

Abstract

Reconfigurable distributed antennas and reflecting surface (RDARS) has emerged as a transformative solution to address the stringent requirements of future wireless networks. By combining distributed active antennas with reconfigurable passive reflecting surfaces

RDARS integrates the advantages of both active transmission and passive wave control in a cost-effective and energy-efficient manner. This hybrid architecture enables enhanced coverage

improved spectral efficiency

and seamless support for integrated communication and sensing. In this article

we first introduce the fundamental architecture and working principles of RDARS

followed by practical benefits and comparisons with recently proposed intelligent surface variants. We then highlight the signal to noise ratio (SNR) gains in representative applications of RDARS-aided communication and sensing scenarios

where RDARS demonstrates clear advantages over conventional reconfigurable intelligent surfaces. Finally

we outline key challenges related to practical implementation and resource allocation

and discuss potential research directions. With its unique hybrid mode synergy

RDARS is envisioned to play a pivotal role in shaping the evolution of next-generation intelligent communication systems.
